Constructor Summary

ElementNotSelector(ElementSelector invertedSelector)
Select if selector says "no", don't select if selector says "yes".

Method Summary

boolean	couldSelectElement(java.lang.String path, int startIndex, java.lang.String uri, java.lang.String localName, java.lang.String qName, org.xml.sax.Attributes attrs) Signals that the element could be selected.
int	getEndMark(int startIndex)
void	processCharacters(java.lang.String path, char[] ch, int start, int length) subclasses can override this to select based on contents of cData.
void	processChildElement(java.lang.String childPath, ElementSelector.ElementData parentElement, java.lang.String uri, java.lang.String localName, java.lang.String qName, org.xml.sax.Attributes attrs) subclasses can override this to select parent tag based on contents of child tags.
void	processChildElement(java.lang.String childPath, int startedAt, java.lang.String uri, java.lang.String localName, java.lang.String qName, org.xml.sax.Attributes attrs) This method is used to determine if the presence of a certain child tag should cause the parent (or ancestor tag) to be selected too.
void	reset()
void	setEndMark(java.lang.String path, int endIndex) Called by SAXDeleteFilter to mark end of processed element.
boolean	shouldSelectElement(int startIndex) Negates the contained Selector's decision.

Constructor Detail

ElementNotSelector

public ElementNotSelector(ElementSelector invertedSelector)

Select if selector says "no", don't select if selector says "yes".

Parameters:

invertedSelector - ElementSelector whose decision we are inverting.

Method Detail

couldSelectElement

public boolean couldSelectElement(java.lang.String path,
                                  int startIndex,
                                  java.lang.String uri,
                                  java.lang.String localName,
                                  java.lang.String qName,
                                  org.xml.sax.Attributes attrs)

Description copied from class: ElementSelector

Signals that the element could be selected. Uses contained ElementComparator to check if the element is deletable by this ElementSelector.

Overrides:

couldSelectElement in class ElementSelector

setEndMark

public void setEndMark(java.lang.String path,
                       int endIndex)

Description copied from class: ElementSelector

Called by SAXDeleteFilter to mark end of processed element. If the element is going to be selected, we need to save it because a new sibling element could come along.

Overrides:

setEndMark in class ElementSelector

processChildElement

public void processChildElement(java.lang.String childPath,
                                int startedAt,
                                java.lang.String uri,
                                java.lang.String localName,
                                java.lang.String qName,
                                org.xml.sax.Attributes attrs)

Description copied from class: ElementSelector

This method is used to determine if the presence of a certain child tag should cause the parent (or ancestor tag) to be selected too.

Overrides:

processChildElement in class ElementSelector

processChildElement

public void processChildElement(java.lang.String childPath,
                                ElementSelector.ElementData parentElement,

                                java.lang.String localName,
                                java.lang.String qName,
                                org.xml.sax.Attributes attrs)

Description copied from class: ElementSelector

subclasses can override this to select parent tag based on contents of child tags. using elementData.setSelecting( )

Overrides:

                              int length)

Description copied from class: ElementSelector
